Medical Suturing Needle

Abstract

Provided is a medical suturing needle or a round needle having a circular section, which is balanced between the magnitude of an insertion resistance to living tissues and the difficulty in damaging gloves, thereby to improve the safety. The medical suturing needle (A) comprises a ball-shaped needle tip ( 1 ), a tapered portion ( 2 ) continuing to the needle tip ( 1 ), and a trunk portion ( 3 ) continuing to the tapered portion ( 2 ). The ball of the needle tip ( 1 ) has a diameter of 0.25 mm to 0.34 mm, and the tapered portion ( 2 ) has a tapering angle of 8.5 degrees to 9.4 degrees.

1 . A medical suturing needle comprising a ball-shaped needle tip, a tapered portion continuing to the needle tip, and a trunk portion continuing to the tapered portion, wherein
 the ball of the needle tip has a diameter in a range of between greater than or equal to 0.25 mm and smaller than or equal to 0.34 mm, and the tapered portion has a tapering angle in a range of between greater than or equal to 8.5 degrees and smaller than or equal to 9.4 degrees.   
     
     
         2 . The medical suturing needle according to  claim 1 , wherein cross-sectional shapes of the tapered portion and the trunk portion are formed to a circle, and the trunk portion has a thickness in a range of between greater than or equal to 0.7 mm and smaller than or equal to 1.4 mm.
